BUSHING FOR PUMP-RODS.,

SPECIFICATION form'ng part of Letters ?atent No. 655,395, dated August '7, 1900. Application filed March 19, 1900. Serial No. 9,149. (No model.)

To all wir/0777, 't may concerm Be it known that I, GEORGE H. CUSHING, of Seneca Falls, in the County of Seneoa, in the State of New York, have invented new and useful Improvements in Bushings for Pump- Rods, of which the following, taken in connection with the aocompanying drawings, is

a full, clear, and exact description.

My invention relates to pumps for operation by manual or windmill power; and the object is to provide means whereby the length of the stroke may be increased when the handle is disconnected from the rod and the latter is connected with the windmill mechanism.

To this end my invention consists in the conbination of the cap and bracket on the top of the pump and the punp-rod having round and square or rectangular or fiattened portions with a bushing Secured in the apertnre of the horizontal part at the upper end of the bracket having a vertical square or fiattened hole at its upper end and terminatingin a round hole at its lower end; and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the clairns.

In the drawings hereto annexed and forning a part of this specification, Figure 1 is a side elevation of the upper part of a pump provided with my invention. Fig. 2 shows the bushing detached. Fig. 3 is an enlarged vertical longitudinal sectional View of the same. Fig. e is the lower end view. Fig. 5 shows a pump-rod formed of a square or fiattened rod and a round rod joined together by a threaded coupling. Fig. 6 shows a sectional View of the coupling, and. Fig. 7 shows the lower end view of a modified form of bushing' when the coupling is used.

Referring specifically to 'the drawings, A is the cap and bracket on the upper end of the pump.

B is the bushing and guide in the aperture through which the pump-rod works.

C is the vertically-reoiprocatingpump rod, having a square or flattened upper portion and a round lower portion.

D is the handle connected to the rod, and E is the link between the handle and the hori 'zontal extension a at the base of the bracket. The pump-rod in Fig. 1 has its square and round portions c' and c, respectively, integral or welded together, and the inner end of the handle is connected to the square portion just above the round portion. By means of the handle and with the braoket A usually enployed about an eight-inch stroke may be.

given to the rod. As it is desirable to gain a longer strokewhen Operating the same pump by a windmill (not shown) I disconnect the handle from the rod as usual and provide the bracket with an aperture of a size to receive a bushing B, the bushing being elongated or extended upward a considerable distance above the bracket and provided with a square hole CZ at its upper end for a guide for the square portion of the pu nip-rod and terminating at its lower end. in a round hole d' for a guide for the round portion of the rod when it is raised up' within the bushing.

Figs. 3 and 4 clearly show the form of the bushing on its interier.

F indicates the body and air-chanber of the punp.

l an aware that it is old to provide a bushing in the bracket for the pump-rod, but it is never extended above the rim or fiange b, and has always had a square hole throughout its length for the pump-rod and not both a square and round hole. The bushing is preferably held in place in the bracket by a setscrew b'.

W'hen the square and round portions of the pump-rod are not welded together, but joined by a threaded coupling G, as shown in Figs. 5 and 6, the bushing has an enlarged round hole in its lower end` to receiye the coupling, which is somewhat larger in diameter than the round rod and in some cases may be larger than the width of the square or rectangular rod, as shown in Fig. 7 ,which shows a view of the lower end of the modified form of bushing.

The handle is detached from the pump-rod by withdrawing the pin or bolt e.

Having described my invention, what I i claim as new, and desire to secure by Letters Patent, is-

1. The combination of the bracket and the pump-rod having round and square or flattened portions, with a bushing secured in the horizont-al upper end of the bracket having a IOO vertical square or flattened hole in its upper end and a vertical round hole in its lower end, as and for the purpose described.

2. The combination of the braeketon the upper part of a pump to support the punprod, the upper end of the braoket having a horizontal extension adapted to hold a bushing, a bushing Secured in the extension and eXtending above the same, saicl bushing having a square or fiattened hole in its upper end and a round hole in its lower end, and the pump-rod passing through the bushing hav ing a square or fiattened upper portion and a round lower portion, as and for the purpose described.

3. The combination of the braoket on the upper part of a pump, the upper end of the braeket having a horizontal extension adapted to hold a bushing, a bushing Secured in the extension and extending above the same, said bushing, having a square or fiattened hole in its upper end and a round hole in its lower end of a diameter equal to or greater than the width of the square or fiattened hole,

and a pump-rod having round and square or flattened portions to slide in the bushing, as set forth.

4. The oonbination of the braoket on the upper part of a pump, the upper end of the braoket having a horizontal extension adaptecl to hold a bushing, a bushing Secured in the extension and extencling above the same, said bushing, having a square or flattened hole in its upper end and a round hole in its lower end of a diameter equal to or greater than the Width of the square or fiattened hole, and a pump-rocl passing through the bushing,forned of a round rod and a square or flattened rocl in line with each other and joined together by a threadecl ooupling, substantially as shown and described.

In testimony whereof I have hereunto signed my name.

GEORGE H. CUSHING.
